SAMUEL F. PATTERSON, OF BALTIMORE, MARYLAND.

POWER-Loom SPECIFICATION forming part of Letters Patent No. 722,248,dated March 10, 1903.

Application led July 25, 1901- Serial No. 69,714. (No model.)

To all Zoli/0711. it 71mg concern:

Be it known that I, SAMUEL F. PATTERSON, a citizen of the United States,residing at the city of Baltimore, in the State of Maryland, haveinvented certain new and useful Improvements in Power-Looms, of whichthe following is a specification.

This invention pertains to power-looms; and it consists, primarily, incombining with the usual weaving apparatus or loom proper jacquardmechanism and automatic devices for renewing the filling in the shuttlewhenever it becomes exhausted or when the filling thread or yarn breaks.

The invention further consists in certain novel features, details, andcombinations hereinafter set forth, whereby the invention thus generallystated is efficiently embodied and carried into practice.

In the accompanying drawings, Figure l is a perspective view of a loomembodying my invention; Fig. 2, a top plan view of a portion thereof,showing more particularly the mechanism for supplying lling to theshuttle; Fig. 3, a vertical section on the line c rc of Fig. 2; Figs. 4Eand 5, detail views of the detector mechanism, which serves to ascertainwhether the shuttle is in proper position to receive a fresh bobbin,spindle, or cop and determines accordingly whether or not certain otherparts shall go into operation; Fig. 6, a diagrammatic top plan View ofthe driving and controlling mechanism of the loom intended to show thegeneral and relative arrangement of parts; Fig. 7, a detail view of thefeeler and latch mechanism.

Prior to my invention jacquard mechanism of different types or styleshad long been employed in connection with looms to produce figure orpattern effects. So, too, but for a shorter time automatic mechanism forintroducing into the shuttle a fresh or filled bobbin, spindle, or copwhen necessaryhad been combined with weaving mechanisms or looms properadapted to produce plain fabrics only. Each of these attachments orappliances had its useful purpose and function and each added greatly tothe efficiency or capabilities of the loom in one or another way. I havecombined these several mechanisms in one structure, whereby theproduction of figured fabrics is greatly increased over the productionof looms having jacquard mechanism used prior to my invention for makingthe same fabrics, and the cost of such production is thereby alsodecreased.

Referring again to the drawings and first to Fig. l, A indicates theloom as a whole, B the jacquard mechanism, and O the automatic bobbin,spindle, or cop feeding mechanism, which constitute the main elements orgroups of elements embraced in the novel combination constituting myinvention.

In themselves the several mechanisms just indicated may be of any usualor approved construction, though I have selected and have represented inthe drawings those types of each which I deem best suited to the purposein view.

Referring now not only to Fig. l, but to the other figures in whichparts mentioned may be found, the loom A will be seen to comprise theusual frame provided with a crank-shaft D, the cranks of which connect,by pitmen or connecting-arms E, with the swords or carrying-arms F ofthe lay G, a picker-shaft II, with the usual cams, picker-sticks andintermediate picking-shaft, a shuttle I, and the customary harness,beams, dac., employed in a power-loom having jacquard mechanism.

The Draper loom, being one well and favorably known, is here taken as anillustrative type, the customary harness or heddle-frames and mechanismfor operating the same, however, being done away with and the customaryharness of a powerloom having jacquard mechanism being introduced inplace thereof.

It will be seen upon referring to Figs. l and 6 that the crank-shaft Dis furnished at one end with a wheel J, having a crank-pin a, and thatpicker-shaft l-I is extended beyond its usual point of termination inlooms of the class illustrated and furnished with a double crank b c.These several cranks a, ZJ, and c are designed to actuate the jacquardmechanism, the crank-pin a being connected by an upright rod d with thelever K, which reciprocates or moves facewise the perforate prismaticboX or so-called cylinder controlling the horizontal needles orcross-Wires, and the cranks h and cbeing connected by rods e and f withthe levers L and M, which alternately elevate and lower the griffs orICO and c are carefully proportioned and arranged with reference to therelations existing between the loom proper and the jacquard mechanism.The two shafts D and H are geared together and maintain thepredetermined relation and times of action.

Figs. 2 and 3 illustrate the magazine or battery for holding a series ofbobbins, spindles, or cops duly wound with the fillingthread or yarn,together with the mechanism for forcing one bobbin, spindle, or cop fromthe magazine into the shuttle, and thereby displacing or ejecting aspent bobbin or filling-carrier or one the filling-thread of which hasbroken. This mechanism is of wellknown construction and will bedescribed only so far as may be useful or necessary to a clearunderstanding of the combination of the several groups of mechanismsabove noted. magazine or battery comprises first a vertical plate ordisk N, rising from a bracket O, bolted or otherwise made fast upon thebreast-beam .P and formed :with an overhanging horizontal flange g,which extends nearly around the circumference of the disk, terminatingat a point below and nearly in vertical line with the center of saiddisk and at a short distance from a stop or abutment h, formed upon thesupporting-bracket or the plate itself. From the center of plate or diskN projects a horizontal stem or spindle t', which constitutes an axlefor a drum or carrier Q, comprising a peripherally-notched disk orheady' and a radially grooved or recessed disk or head 7c, connected andspaced by a tubular sleeve l, which fits and turns upon the spindle 1I.The notches -m of the disk or head j are of a size and form to receiveand hold the heads of the bobbins or spindles R, Whose tips are carriedin the radial grooves nof disk 7c. The heads are retained in position bythe overhanging Hangs g, and the tips are retained in the radial groovesn by curved spring-tongues 0, secured in the grooves and projectingoutward somewhat beyond the periphery of the disk 7c, so that they maybe readily pressed back to permit insertion of a full bobbin or spindle.Projecting beyond disk lo and concentric therewith is a supporting-platep for the weft or filling threads of the several bobbins, spindles, orfilling-carriers of the magazine or battery. The periphery of thissupporting-plate is fashioned, essentially, like a ratchet-wheel, therebeing as man v radial faces as there are grooves in the disk 7c.Concentric vwith and projecting slightly beyond supportp is a boss orspool q, about which the ends of the illingthreads are wound afterpassing from the filling-carriers over the supporting-platep. By beingthus wound upon the boss or spool each thread or yarn is caused to drawfrom its spindle or carrier as the latter, inserted into the shuttle, iscarried through the shuttle-race or across the lay. Between thetermination of the guard or flange g and the stop or abutment h is leftspace sufficient for the passage of the head or enlarged end of a bobbinor spindle R. S indicates an ejector by which the bobbins, spindles, orcops are one at a time removed from the magazine or battery anddelivered into the shuttle. This operation is effected at that instantwhen the shuttle is in its box at that end of the loom at which themagazine is located and when said box and its contained shuttle areimmediately beneath the opening left between the flange g and abutment77 as indicated in Fig. 3. There is at this instant the brief dwell ormomentary rest of the lay incident to the cranks passing the centerand'reversing the motion of the lay, and this is of course the mostavailable time at which to remove one bobbin or spindle andinsertanother. TheejectorSispivotallysupported upon the bracket orupright plate N, its inner end being held up by a spring r and occupyinga position immediately over the lowermost spindle or bobbin R of thebattery or magazine, as seen in Fig. 3. Carried by the lower arm of theejector, which as a whole is in the form of an elbow-lever, is aswinging member s, upon which is adjustably mounted a notched block t. Aspringt', Fig. 6, coiled about the pivot by which the member s isattached to the ejector-arm, tends to swing the member s inward, andthereby to elevate the notched inner end of` block t. This tendency iscounteracted and normally overcome by a hook or finger u, adjustablysecured to a depending arm of a T-shaped lever T, pivoted upon a stud oraxle a', projecting from the plate or upright N, said finger or hook uengaging a stud c on the block t or its carrier,-as shown in Fig. 3.Hook or finger u occupies under different conditions the positions shownby full and dotted lines in Fig. 4 and by full lines in Fig. 5, itsnormal position being that shown by full lines in Figs. 3 and 4, so thatthe block t normally stands in the position shown in said Fig. 3. Hookor finger u is retained normally in said position through 'the stress ofa spring w, acting through a lever o0 and link y, which latter isslotted at its upper end and hung upon a stud z, projecting from an armof lever T on the opposite side of the pivot-axis of said lever fromthat of the arm which carries hook or finger u. A third arm b risesvertically from lever T and isconnected by a link c' with adetector-lever U, which normally occupies the position indicated by fulllines in Fig. 4. This detector'arm or lever is pivotally supported uponan arm or bracket of the magazine or battery frame and is carried to andheld in the position indicated in Fig. et by a spring d', coiled aboutthe stud on which it is pivoted, fixed at one end to said stud andbearing at the other end against the lever U. Spring d exerts forcesufficient IOO IIO

to swing the detector U and through itand link c the lever T and hook orfinger u to the positions indicated by dotted lines in Fig. 4, providedsaid parts be not restrained or held against the action of spring d byother means; but, as aboveindicated', springw, acting through lever :nand link y, ordinarily exerts a preponderating force and holds the partsin the positions shown by full lines in Fig. 4. Lever is secured upon arock-shaft e', carried in hangers or bearings attached to thebreast-beam P or to other convenient su pports. The rock-shaft e extendsacross the front of the machine and carries at the end opposite that atwhich lever :n is located an upright arm f'. (Seen in Figs. l, 3, 4, 5,6, and 7.) The upper end of arm f is bent laterally and then inward,terminating just above the top face of the breast-beam and in positionto be engaged by the iilling-feeler slide V (on the breast-beam) whensaid slide is moved outward, as happenswhen the filling thread or yarnbreaks or gives out. This slide is shown in Figs. 6 and 7 and carries atits inner end the pivoted filling-fork w, which, as the lay swingsoutward, encounters or is encountered by the filling-thread, if the samebe present. The weft-fork is of the form shown in Fig. 7, comprising ahorizontal member and a substantially vertical member, which latter liesin the path of the thread or filling as the lay swings outward. Thehorizontal or outer member of the fork is here shown in the form of abail to engage a hook h2, pin-jointed to the lever or hammer h, carriedand oscillated by the lever t', in turn actuated by camj on the shaft H.So long as the filling is uninterrupted through depletion or breakage itwill on the outward throw of the lay encounter the weft-fork W and liftits horizontal member, so as to prevent engagement with the hook h2, andconsequently prevent backward movement of the slide in or upon which thefork is pivoted. If, however, the thread or filling fail from any cause,the fork W will not be acted upon, and its horizontal portion beingunlifted its bail will lie in the path of the hook h2 and will inconsequence engage said hook and cause the fork and the slide V, inwhich it is lnounted, to be moved backward. In this moving backward theslide encounters the arm f' of rockshaft e, turning said shaft andlifting arm or lever and link y, overcoming in so doing the resistanceor stress of spring fw. Owing to the slotting of the link y the liftingthereof does not in itself aect the three-arm lever T; but it leavessaid lever free to be moved through its connection with the detector U,actuated by spring d. If the shuttleis properly positioned within theshuttlebox beneath the magazine at the time the hammer h swings outwardand after failure of the weft thread or yarn, the elevation of link y inthe manner just described will be followed by the swinging of detector Uto the position indicated by dotted lines in Fig.

4; but should the shuttle not be properly positioned within the box itwould be encountered by the detector U, as in Fig. 5, and thus the partswould be precluded from reaching the position indicated by dotted linesin Fig. 4. Assuming that the shuttle has reached its proper position inthe shuttlebox and that the weftthread has failed, thereby bringingabout a movement of the parts to the position indicated by dotted linesin Fig. 4, hook or finger it will thereby have relieved stud v ofpressure and will have permitted the spring t' to turn or swing thecarrier s and block to a position where the notch r in the end of saidblock will be in the path of a projection 7c' on an arm carried by thelay G. When the block is brought to the position indicated, the horn orprojection 7s', encountering the block t, will cause the ejector S toswing about its pivot or axle, and

thereby to press its head or ejecting portion against the spindle orbobbin of the magazine, which at that moment lies against the abutmentor stop h. The movement of the ejector is such as to carry the bobbin orspindle out of the notch m of the disk or head j and out of the groove nof disk 7c and to force said bobbin downward into contact with thebobbin in the shuttle I. As is usual with this magazine or batteryfeeder the shuttle is of the self-threading variety and is open at topand bottom and holds the bobbin by means of springs having slightlyconcave seats to receive the circumferential rings or beads formed uponor applied to the head or enlarged end of the bobbin, so that the bobbinis free to enter at one side of the shuttle and leave at the oppositeside, or, in other words, to pass directly through if pressure beapplied sufficient to overcome the holdingsprings. The shuttle-box islikewise out through at the bottom to permit the delivery through it ofthe ejected bobbin or spindle, as indicated in Fig. 3.

The usual devices for stopping the loom when a warp-thread breaks orwhen the shuttle does not reach its proper position at the end of theshuttle-box and a belt-shifter, brake, and like parts will or may beprovided; but as these are of well-known construction it is not deemednecessary to enter into a further or more detailed description of them.The same is true of other details-such as the tip-support for the bobbinor spindle in position to be delivered from the magazine or carrier, themechanism for rotating said carrier and arresting it at the properpoint, dac. As to all these matters any suitable construction andarrangement known in the art may be employed-such, for instance, as usedin the Northrop magazine or batterylooms now extensively in use andillustrated in United States LettersPatenttoJ. H. Northrop, dated June23, 1891, and numbered 454,810. The

magazine may be of the rotary type shown or of the hopper style.

Asis usual, the overhanging flange gis here IOO IIO

represented as supplemented by or provided with a spring member g',secured to the rigid flange g and requiring the exertion of moderateforce to press its end back sufficiently to permit escape 0f a bobbin,cop, or spindle from the rotary holder.

The take-up mechanism used in connection with the cloth-beam and thelet-off mechanism used with the warp-beam are not shown in the drawings,and some other details not necessary to an understanding of theinvention claimed are likewise omitted to avoid confusion.

Having thus described my invention, what I claim is- 1. In combinationwith the weaving mechanism proper of a loom, an automatic mechanism forsupplying weft or filling to'the shuttle; jacquard mechanism forcontrolling the harness of the loom; and intermediate connectionsbetween such mechanisms, substantially as described.

2. In combination with the weaving mechanism proper of a power-loom,jacquard mechanism for controlling and actuating the harness thereof; amagazine or battery for containing a supply of filled bobbins orspindies;` mechanism for automatically delivering a filled bobbin orspindle to and ejecting an empty one from the shuttle; and connections,substantially such as shown and described, between such mechanisms.

3. In combination with the weaving mechanism proper of a power-loomhaving cranks a, b and c; jacquard mechanism connected with and actuatedby said cranks; and automatic mechanism for supplying filled bobbins orspindles to the loom-shuttle, substantially as described.

In testimony whereof I have signed my name to this specication in thepresence of two subscribing Witnesses.
